Be it known that 1-, ANNA WINTER; a citizen of the United States, and residen 1' New York city, in the county and State of New York, have invented certain new end useful Improvements Safe-Door Traps, of which the following is a specification.

The object of the resentinyentien is to provide a trap in e spindle lock, such eson d ors; in whieh concealed arms or jawsiw ll be? Teleased the turning of the spindle by 1;; person who does not know the roper operation, whereby the jaws will 0 ose on the hen-d or arm of such person, and remain looked in such position until released.

A further ohjeot oi th e invention is to provide an errangernentof this'rehwrfiieter in which the jaws can bereleased only from the inner side of the door or member, that is accessible only by some one who; knows the combination opening the door;

In the accompanying drawings showing one embodiment of my invention, Figure 1 is a front elevation of the device.

This invention comprises gessentiaglly s look, especiallyof the spindle type, a pair of jaws normally concealed in "the member to he brought together adjacent the spindle, and means whereby the operation ofgthe spindle or look, except in a certain peeiilier manner, will result in the jaws being brought together. 1 V

As shown in the dmwi .,;n.; neinl9er t V. wevided with a lock in the torn: QZElErSPi n3 eon? trolled by a handles, and which rotates in the door. it is to be understood thet this spindle will operate a combination any well known manner. A pairof jaw mem} bers 5 and 6 are hinged together at 7 snd'8 to surround the spindle an d are normally concealed in ehanrfelsQend i-n'th'e door or member. The jaw members are shown providedwith bowporti-ens 1; and i2 that serve to surround the wrist or arm ofithe person tobe caught, by engagement ef'tlfeir nner ends13 and 14,.see E g fi. jaw 5 has anyextensien or erniil5 pro eeting j r "brgci fimn orn emmm.

through'the'door and engaged l) a coil spring 16 that will serve to swing his arm froln the concealed position toward the axis of the spindle 3. The other jew 6 has a similar arm 17 engaged by e coil spring 1 8 to swing it toward the axis of the s indle;

whereb the jaws ere broughtfrom t e com cealed position to engage the wrist of-a personigttemiptingto tnrn thespindle. Means ere ptlfoyidedfifior looking the jaws in. this closed position, shown in the form of e SpringpaWl 19 carried by the arm 15, that rides over is fixed segment 20, in. the doom and prevents reverse movement of the jaw when closed. Asimilar spri-n pawl 21 on the other arm 17 engages a xed segment 22011 the door; whereby the jaws will be locked in their closed position and firmly grasp the mister arm of the operator. 1t Willbeobserved that the pawls are located on lthe inner side of the door, and when the door is closed are not accessible to release the person caught, until the door is opened, when pawl can be lifted from its segment and the jaws released. 1

Ellhejews are. normally retained in the open position by a. trip devioe, that is released on'turning the spindle, except upon special mani ulation of the spindle. On the side 0 the door is hin d a lever 23, emnged to engegethe new edend 24 i. the jaw 17:, and retain the jaw in the lopen .positien until the lever is shifted. A s'nnilar lever 25 engages the arm 15 to hold the jaw .5Ginwthe concealed open position. spindle 3 projects through the door and has a. disk 26 secured on its inner portion, thetis rovided with notches 27 and 28 at opposite portions. A second disk 29 terns free on the spindle 3, and has notches Bonnier, turning this disk will =..;-stei';. respebtively'" with the notches 27 and 28. The inneren'ds of thelevers 23 and =25 are provided with lugs 32 and 33., that wrepaused, b .coil springs 34 and 35, on the levels, to; pressed into the registering notches ofztlie. two disks npo'n turning the Spindle and disksto such a relative pos tion. But innny other relative position of the disks. exeeiat when their notches rfig t r end ame loeeted directly-opposite these lugs, theaspringsiwill press thel on the levers ngatinst the-j ripherie's of. tie diw, This will retfiiikt lei-levers infthe described, itions in which theyewil-lserve to 1101 ,Zthe

cealed positions. Normally the spindle-is set in this manner, so that when turnedin,

either direction by the handle to bring the registering notches of the two disksoppo;

' when access is had to the inner side of the door. Means are provided for locking the loose disk-29 to the other disk 30 carried by the spindle, and releasing them, at the will of the operator. A coil spring 36 between shoulder 40 and spindle 3 and 'a flange 41 on sleeve 42, serves to press the spindle outwardly and hold the disks together, and cause a stud 37 on the disk'26 to enter recesses 38 or 39 in the disk '29. By pressing inwardly on the handle 4, the stud will release the inner disk and the disks may be turned relatively, so that this stud can be caused to enter either of these recesses. The latter are so arranged that when the stud'is in the recess 38 the disks have their peripheral airs of notches in register; and upon pressing inward on the spindle this relative position of the disk is changed and the stud can be brou ht to enter the recess 39, which will lock t e disks together with their notches out of register.

A mark can be placed on the handle as at 40, and marks placed on the door as at 41, to indicate the relative positions of "the disks.

are positioned with their notches out of register with the lever lugs, that will hold the levers in position to engage the jaws and retain them in the open and concealedposition. The disks are manipulated by the spindle so that they are brought with their pair of notches registering, but not adjacent the lugs on the levers. This is the set position of th device, and any person not understanding the proper operation, on turning the spindle and handle for not less than a quarter turn, will bring the registering notches to engage the lugs on the levers that will spring into the notches and release the jaws, and the latter will at once close on the operator. 7 The door being closed, the pawls will hold the jaws in the closed position and can not be released until the door is opened.

' 7 But a person understanding, the operation,

will first push the spindle inwardly' and'tfhen give it a torn tobring the marks tomgister and' can readily ascertain that the'stud on the inner disk will enter theother di sk recess and thus loclr the disks together with their pairs of notches out of register. Thereupon the'spindle can be given any In the operation of the device the disks number of turns in either direction, and since the lugs 32 and 33 are wide enough to ride on the edge of both disks, they can not 'cnteraeither of the notches and hence the levers can not swing. It is only by bringing the-pairs of notches to register that the lugs will enter such notches andshift the lovers. "When a person has been trapped by the jaws, the person knowing the combination will operate the spindle by pushing in on-the handie and inner diskand turning it in the inward position through the proper combination, that will permit the door to be opened. Then the pawls can be pulled back to free the jaws and the person caught will be released.
